Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices
Advanced Materials, EarlyView.A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.

FCS-MPC for four-switch three-phase AC-DC converters with DC-link capacitor voltage balancing
Journal of Measurement Science and Instrumentation, 2019 Due to the decrease in the number of switches for the four-switch three-phase alternating current-direct current（FSTP AC-DC） converter, it can easily lead to DC-link capacitor voltage imbalance and the system stability reduction.

Advanced Materials Interfaces, EarlyView.Xenon flash lamp annealing modulates oxygen‐vacancy states in 1‐nm‐thick ALD In2O3 transistors within a single 139 µs pulse. The photon‐induced defect engineering shifts the threshold voltage, improves bias‐stress stability, and narrows device‐to‐device variation across 64 devices. Combining pristine and treated transistors yields NMOS inverters with a
